汽车液压制动系统 故障诊断分析与排除 2014年4月  汽车液压制动系统故障诊断分析与排除 摘 要 汽车制动系是用以强制行驶中的汽车减速或停车、使下坡行驶的汽车车速保持稳定以及使已停驶的汽车在原地（包括在斜坡上）驻留不动的机构。随着高速公路的迅速发展和车速的提高以及车流密度的日益增大，为了保证行车安全，汽车制动系的工作可靠性显的日益重要，也只有制动性能良好、制动系工作可靠的汽车，才能充分发挥其动力性能。 本文论述了汽车制动系统的概念、工作原理和它所具有的行车制动系统、驻车制动系统和ABS防抱死制动系统各自间的一些故障，通过这些故障找出其故障的部位以及造成故障的原因，然后针对这些故障给予及时的处理方法，引出了制动系统故障的诊断和检修的重要性。 关键词：汽车制动系统；故障现象；故障原因；故障诊断 Automotive hydraulic braking system fault diagnosis and exclusion Abstract Automobile brake system is used to force the vehicle to slow or stop, make the downhill cars speed stability and to have been suspended in the vehicle in place ( including in slope ) resides not moving mechanism. With the rapid development of highway and speed as well as the increasing traffic density, in order to guarantee the traffic safety, the reliability of automobile brake system is more and more important, only good braking performance, reliable car brake system, in order to give full play to its dynamic performance. This paper discusses some fault between their respective concept, the automobile braking system principle of work and the braking system, driving it with the parking brake system and ABS anti-lock braking system, the failure to find the fault location and the causes of failure, and then give the treatment timely in view of these faults, the importance of diagnosis maintenance and malfunction of the brake system. Key words: automotive brake system；failure phenomena；the cause of the malfunction；fault diagnosis 第1章 汽车液压制动系统的概述 1 1.1液压制动系统的概念 1 1.2液压制动系统的功用 1 1.3液压制动系统的组成、工作原理及分类 1 第2章 汽车制动系统之行车制动故障诊断 3 2.1行车制动系统的结构组成及常见故障部位 3 2.2液压制动系统的常见故障 3 2.2.1制动不灵 3 2.2.2制动失效 4 2.2.3制动拖滞 5 2.2.4制动跑偏 7 2.2.5液压制动的其余故障 8 第3章 汽车液压制动系统之驻车制动故障诊断 10 3.1驻车制动的结构组成及常见故障部位 10 3.2驻车制动的常见故障 10 3.2.1驻车制动效能不良 10 3.2.2驻车制动拉杆不能定位 11 第4章 ABS防抱死制动系统故障诊断 12 4.1制动防抱死系统的结构组成及工作原理 12 4.2制动系统ABS故障诊断与检修 12 4.2.1车轮速度传感器的调整 12
